ITCO 630 AIU ONLINE Unit 5 Purpose of Data Bases Discussion Board

0 comments

I’m working on a computer science discussion question and need an explanation to help me study.

At the end of each unit, DB participation is assessed based on level of engagement and the quality of the contribution to the discussion. DBs allow learners to learn through sharing ideas and experiences as they relate to course content. Because it is not possible to engage in two-way dialogue after a conversation has ended, no posts to the DB are accepted after the end of the unit. Learners must demonstrate an appropriate depth of understanding of course content to receive credit for having submitted substantive posts. Typically, this is achieved with 3–4 strong paragraphs for Main Posts and 2–3 strong paragraphs for Response Posts.

Discuss the following in the Discussion Board:

  • Think of a purpose for creating a database and describe the database. Explain why you would want to use a database for this purpose.
  • What example could you offer that would demonstrate using a subquery?
  • What example could you offer that would demonstrate using a join?
  • In your view, would you prefer using subqueries, or joins, and why?
  • What are some performance considerations when determining whether to use subqueries or joins?
